This functionality is in beta and is subject to change. The design and
code is considered to be less mature than official GA features. Elastic will
take a best effort approach to fix any issues, but beta features are not
subject to the support SLA of official GA features.

Heartbeat provides a command-line interface for running the Beat and
performing common tasks, like testing configuration files and loading
dashboards. The command-line also supports global flags
for controlling global behaviors.

This setting is applied to the currently running Heartbeat process.
The Heartbeat configuration file is not changed.

-c, --c FILE

Specifies the configuration file to use for Heartbeat. The file you specify
here is relative to path.config. If the -c flag is not specified, the
default config file, heartbeat.yml, is used.

-d, --d SELECTORS

Enables debugging for the specified selectors. For the selectors, you can
specify a comma-separated
list of components, or you can use -d "*" to enable debugging for all
components. For example, -d "publish" displays all the "publish" related
messages.

-e, --e

Logs to stderr and disables syslog/file output.

--path.config

details.
